nav_menu_items displaying in 'Recent Posts'

I have added two new Custom post types to my theme, these being photo and photo365.

because of this, when I wanted to display a list of recent posts in a widget – I have to use a custom widget to list what type of posts I wanted it to display

WP_Query(array('showposts' => $number, 'nopaging' => 0, 'post_status' => 'publish', 'ignore_sticky_posts' => true, 'post_type' => array('post', 'photo', 'photo365')));

full function code here custom post

Now, when on my home page – the ‘Recent Post’ widget displays posts of kind post, photo, and photo365

When I vie either via ‘category’ or ‘tag’

it show kind post. photo, photo365 and ‘nav_menu_item’

Now on querying the MySQL database, there are only four posts of post type ‘nav_menu_item’. All of these appear to be entries in the custom menue. (I only have four items in my custom menu)….

How do I stop Recent Posts picking up these menue item?!

Yours Confused…..
